死键问题（急性、分音符等）c++

发布于 2024-08-23 20:37:28 字数 1104 浏览 8 评论 0原文

我目前正在使用 X11 库为 Linux 编写自己的虚拟键盘，但我找不到模拟任何死键的 KeyPress 事件的方法。例如，我尝试使用指定的宏（XK_aacute）编写“á”，但没有任何反应。后来我尝试发送 XK_acute （急性重音宏），然后发送 XK_a，然后再次没有任何反应:(

在 KDE 虚拟键盘“Kvkbd”中可以做到这一点，所以我下载了源代码，但它只支持英语键盘布局

这是我的测试代码：

#include <X11/Xlib.h>
#include <X11/keysym.h>
#include <X11/extensions/XTest.h>
#include <iostream>

int main(){
 Display *display;
 unsigned int keycode;
 unsigned int keycode1;
 display = XOpenDisplay(NULL);

 keycode = XKeysymToKeycode(display, XK_aacute); 
 XTestFakeKeyEvent(display, keycode, True, 0);
 XTestFakeKeyEvent(display, keycode, False, 0);

 keycode1 = XKeysymToKeycode(display, XK_acute);
 XTestFakeKeyEvent(display, keycode1, True, 0);


 keycode = XKeysymToKeycode(display, XK_a);
 XTestFakeKeyEvent(display, keycode, True, 0);
 XTestFakeKeyEvent(display, keycode, False, 0);

 XTestFakeKeyEvent(display, keycode1, False, 0);


 keycode = XKeysymToKeycode(display, XK_D);
 XTestFakeKeyEvent(display, keycode, True, 0);
 XTestFakeKeyEvent(display, keycode, False, 0);
 XFlush(display);
}

任何帮助或想法将不胜感激

I'm currently writing my own virtual keyboard for linux using the X11 lib and i just can't find the way to simulate a KeyPress event of any dead keys.
I'd tried , for example, to write "á" using the asigned macro, which is XK_aacute, and nothing happens.
later i'd tried to send XK_acute (the acute accent macro) and then XK_a, and again, nothing happens :(

In the KDE virtual Keyboard "Kvkbd" it's possible to do this, so i downloaded the source code, but it only supports the english keyboard layout

Here is my test code:

#include <X11/Xlib.h>
#include <X11/keysym.h>
#include <X11/extensions/XTest.h>
#include <iostream>

int main(){
 Display *display;
 unsigned int keycode;
 unsigned int keycode1;
 display = XOpenDisplay(NULL);

 keycode = XKeysymToKeycode(display, XK_aacute); 
 XTestFakeKeyEvent(display, keycode, True, 0);
 XTestFakeKeyEvent(display, keycode, False, 0);

 keycode1 = XKeysymToKeycode(display, XK_acute);
 XTestFakeKeyEvent(display, keycode1, True, 0);


 keycode = XKeysymToKeycode(display, XK_a);
 XTestFakeKeyEvent(display, keycode, True, 0);
 XTestFakeKeyEvent(display, keycode, False, 0);

 XTestFakeKeyEvent(display, keycode1, False, 0);


 keycode = XKeysymToKeycode(display, XK_D);
 XTestFakeKeyEvent(display, keycode, True, 0);
 XTestFakeKeyEvent(display, keycode, False, 0);
 XFlush(display);
}

Any help or idea will be much apreciated

我刚刚发现 ØØ

#include <X11/extensions/XTest.h>
#include <X11/keysym.h>
#include <X11/Xlib.h>
#include <iostream>

int main(){
 Display *display;
 unsigned int keycode;
 unsigned int keycode1;
 display = XOpenDisplay(NULL);

 keycode1 = XKeysymToKeycode(display, XK_dead_acute);
 XTestFakeKeyEvent(display, keycode1, true, 0);


 keycode = XKeysymToKeycode(display, XK_A);
 XTestFakeKeyEvent(display, keycode, true, 0);
 XTestFakeKeyEvent(display, keycode, false, 0);

 XTestFakeKeyEvent(display, keycode1, false, 0);

 XFlush(display);
}

我使用了错误的宏

i just figured out ¬¬

#include <X11/extensions/XTest.h>
#include <X11/keysym.h>
#include <X11/Xlib.h>
#include <iostream>

int main(){
 Display *display;
 unsigned int keycode;
 unsigned int keycode1;
 display = XOpenDisplay(NULL);

 keycode1 = XKeysymToKeycode(display, XK_dead_acute);
 XTestFakeKeyEvent(display, keycode1, true, 0);


 keycode = XKeysymToKeycode(display, XK_A);
 XTestFakeKeyEvent(display, keycode, true, 0);
 XTestFakeKeyEvent(display, keycode, false, 0);

 XTestFakeKeyEvent(display, keycode1, false, 0);

 XFlush(display);
}

i was using the wrong macro
